Hidden Code Reveals Your Pixel Phone May Soon Listen To Every Conversation You Have

Google's next Pixel feature wouldn’t just name the coffee shop song you’re vibing to. It would remember what you said there, too.

Code buried in a recent Android System Intelligence update for the Pixel 10 points to a tool called "Audio Memory," and one line in its setup screen reframes a fear people have carried for years: is your phone listening to you? The feature's own onboarding text says it will "keep track of what you hear throughout your day, from the music around you to your important conversations."^[1]

Nothing has shipped yet. This is pre-release code spotted in a teardown, and Google may never launch it.^[1][2] But the wording is a good reason to check what your phone already hears.

Below, we break down what Audio Memory would actually do, what is real versus speculation, and the settings that put you back in control today.

What Google's "Audio Memory" actually does

Developers at 9to5Google found the feature, codenamed "blueflax," in the latest version of Android System Intelligence for the Pixel 10. Audio Memory looks like an expansion of Now Playing, the tool Pixel owners already use to identify songs playing nearby. The teardown shows it folding song recognition into a broader background service that listens for audio and hands it off to other apps.

The conversation-tracking line is the part that stands out. Android Authority notes that the reference to "important conversations" appears only once in the code, suggesting Google may be aiming for something like an ambient AI note-taker that transcribes what it hears and turns it into notes. That capability is not visible yet, and the screens developers managed to surface only cover music recognition.

Google did build a privacy line into the code. The same setup text says "background conversations and audio are never sent to Google," and the service is designed to run on the device through Private Compute Core rather than in the cloud. However, this is work-in-progress code, not a feature you can turn on today, and teardown findings sometimes never reach a public release.

Your phone probably isn't recording you, so why does it feel like it is?

People already believe their phones eavesdrop. In an All About Cookies survey, 70% of people said they were served a targeted ad for something they talked about out loud but never searched for.

That usually comes down to search history, app usage, and location data rather than live audio. A feature explicitly built to track conversations narrows that gap.

Here’s the honest version of how phone listening works today. Your phone listens locally for wake words like "Hey Siri" or "OK Google," and it records and uploads audio only after one of those is triggered. We break down the full mechanics in our guide on whether your phone is listening to you.

Audio Memory would not erase that model, but a tool whose stated job is remembering what you hear deserves a closer look before you tap "turn on."

The catch is that privacy controls only protect you if you use them. Most people leave the defaults untouched. In the same survey, fewer than one-third of people (32%) had turned off their voice assistant's listening features. A new feature is a good reason to finally check yours.

How to stop your phone from listening right now

You do not need to wait for Audio Memory to take control of what your phone hears. The steps below work on the features available today.

For voice assistants beyond your phone, our guide on how to stop Alexa from listening covers smart speakers and other home devices. 

If you use a Pixel or other Android phone:

1. Open the Google Assistant settings, tap General, and toggle Google Assistant off.
2. Go to myactivity.google.com, open Activity controls, and turn off "Include audio recordings/activity" to stop Google from linking voice clips to your account.
3. Delete what is already stored under Google Account, then Data & Privacy, then Web & App Activity, and set it to auto-delete going forward.
4. Open Settings, then Apps, and review which apps have microphone permission. Revoke it for any app that does not need to hear you.
5. Take it a step further and review all your Android security settings to safeguard your privacy.

If you use an iPhone:

1. Open Settings, tap Siri & Search, and turn off the following: "Listen for 'Hey Siri,'" "Press Side Button for Siri," and "Allow Siri When Locked."
2. Manage Siri data in Settings > Privacy & Security > Analytics & Improvements.
3. Review microphone permissions under Settings > Privacy & Security > Microphone, and switch off any apps that don’t need it.

Bottom line

The line between a phone that listens for commands and a phone that remembers conversations is getting thinner. Google is testing a Pixel feature called Audio Memory that would track what you hear during the day, including your conversations. The current code indicates that the audio stays on your device, but that’s not much reassurance.

Even though the feature hasn't launched yet, it’s a good idea to check your voice assistant settings now, delete your stored voice history, and decide for yourself what your phone hears. Learn more about our recommended security apps for Android.
